What are the characteristics of double sphere rubber expansion joint?
The inner rubber layer of the rubber joint is made of high quality rubber with good surface smoothness, and the resistance rate of the medium is not large, so liquid, slurry, granular material and gas pipelines are available. The outer rubber layer is made of high quality aging resistant rubber, which can generally resist various environmental corrosion, especially with aging resistance to ensure the service life of rubber joints, and the surface will not show cracks or fracture layer debonding in certain light conditions.
The inner layer of the double sphere rubber joint is made of high quality polyester cord fabric and hard steel wire welded to form the skeleton layer of the rubber joint, which has good strength to ensure that the rubber joint will not be stretched and torn in the process of use, and can be restored to its original state after shrinking and deforming. In the neck part of the double spherical rubber joint, our company uniquely designs the patented strengthening collar according to the user's embodied use condition, which has good pressure resistance and ensures the weaker part of the rubber joint, especially when it is used in over 2.0MPa pressure, it is necessary to modify this equipment. All the double spherical rubber joints have no weak points in combination with themselves.
The double spherical rubber joints are produced with good elasticity and toughness, and are commonly used in various pipeline compensation, especially in power plants for the compensation of displacement settlement and noise absorption of long distance pipelines with large diameter circulating water pipes. In the desulfurization tower as available in our plant rubber joints because of strong corrosion resistance and high wear resistance, so for the lime slurry pipeline compensation has a very significant role, in the desulfurization tower commonly used. Our double spherical rubber joints have remarkable shock absorption and noise reduction effect in the centrifugal water pump mouth modification, and ensure the sealing of the pipeline, because the rubber joints absorb the vibration of the pipeline and therefore prevent the pipeline bolts from falling down by vibration. Therefore, rubber joints are a very good choice for pipeline shock absorption and noise reduction and compensation for displacement and settlement.
